Question:
Find the scale factor of trapezoid [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] if it is dilated to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex].
Type your result in the empty box provided below.
Answer:
The scale factor is 2
Step-by-step explanation:
Given
See attachment for plots
Required
Determine the scale factor
Using QR and Q'R' as points of reference.
From the attached plot, we have:
[tex]QR = 4\ units[/tex]
[tex]Q'R' = 8\ units[/tex]
The scale factor (k) from [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex]. is:
[tex]k = \frac{Q'R'}{QR}[/tex]
[tex]k = \frac{8\ units}{4\ units}[/tex]
[tex]k =2[/tex]
Use the circle below to find the correct value of x:
Answer:
113°
Step-by-step explanation:
Measure of central angle is equal to the measure of its corresponding arc.
Here, x is the measure of the central angle and 113° is the measure of its corresponding arc.
Therefore, x = 113°

16a - 3y = 12
What are the solutions to this system of equations?
Answer:
( 3 , 0 ) ( 0 , − 6)a = 12 + 3y/ 16Step-by-step explanation:
Add 3 to both sides
16a-3y+3y=12+3y
Simplify
16a=12+3y
Divide both sides by 16
16a/16 = 12/16 + 3y/ 16
a= 12+ 3y/16

Answer:
1.) the range is 42
2.) mean: 69.4, median:63, mode:none
3.) none since they are numbers that can be high but not low.
4.)The outlier is a greater number like the mean is 69 and the median is 63 which is halfway between 63 and 64 it will affect more the mean than the median since it doesn't matter the actual value of the outlier. it just depends on what the outlier is.
5.) the measure of central tendency best describes the set data with the outlier to which there is no outlier.

Answer:
A) 3.6 miles per hour B) 1.44 miles in the last 24 minutes
Step-by-step explanation:
divide 8.64 by 2.4 to get 3.6 to find the mph then divide 3.6 by 60 to get 0.06 to find the miles per minute, then multiply 0.06 by 24 to get 1.44 miles

Enter an equation in the form y = mx +b that represents the
amount of water (y), in gallons, remaining in the pool after x hours. Please help
Answer:
y = -150x + 1600
Step-by-step explanation:
300 gallons in 2 hours = 150 gallons per hour
y = -150x + 1600
The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.
Answer:
± 60
Step-by-step explanation:
aₙ = a₁ * rⁿ⁻¹
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60
The possible values of the 6th term of the sequence ± 60.
The 5th term in a geometric sequence is 120.
The 7th term is 30
We have to determine the 6th term of the sequence.
What is the formula for the nth term of the sequence?[tex]a_n = a* r^n[/tex]
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ ...... (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ ... (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60.
